Unity: The Associated Script Can Not Be Loaded.

for about a week, ive been working on a a project on unity, its a personal game that im doing for fun, and even though ive put time into it really inst to far as to be called aplha, maybe an aplha of aplha of aplha times 10 (5 rooms and little parkour) anyways, about an hour ago when i start up unity to work on it, i see every object that has scripts attach have an error saying “The associated script can not be loaded” i have no idead what this means and im scared ill lose my work, truthfully i can make back all my work in about an hour, since i now know what im doing in unity and how to do it (the first i made a lot of mistakes) but id still rather not lost all of this work for a random reason that might pop up again. how do i fix this? i have not restarted my pc, nor done anything prior to fixing it, just sat here. please and thanks in advance.

This might well be what you’re after although the error isn’t exactly the same it matches what you’re describing:
